LYONS, Colo. –

Update 7:50 a.m.

A grass fire that burned a total of 13.5 acres of county open space overnight was 100 percent contained at 7 a.m., according to the Boulder County Sheriff’s Office.

Fire crews used a controlled burn around the perimeter of the blaze to contain the flames, which never threatened any people or structures in a rural area near Rabbit Mountain.

Officials confirmed today that the fire was sparked by a downed power line.

Power has been restored in Lyons after a downed power line darkened some of the town and started a small grass fire near Rabbit Mountain late Wednesday night.

The Boulder County Sheriff’s Office also said the fire had grown to about 13.2 acres by about 12:15 a.m., but officials said the blaze is under control and didn’t expect it to grow much more during the night. Crews will remain at the scene to monitor the situation until after dawn.


11:52 p.m.

A small grass fire near Rabbit Mountain is about 40 percent contained after the two-acre blaze was sparked by a downed power line Wednesday night.

The blaze is burning in low grass and small shrubs, according to the Boulder County Sheriff’s Office. Crews will monitor the fire until after dawn, officials said, but the fire was not expected to burn through the night. About 30 firefighters from Hygiene and Berthoud are working the fire.

No evacuations have been ordered because of the fire, which is burning in county open space. No structures have been burned and none are threatened.
